Definitions
- the present invention relates to a filling nozzle for use in filling a liquid of high viscosity, such as curry roux or like food, into containers in a specified amount in each container.
- Such filling nozzles comprise a tubular nozzle body having an inlet at an intermediate portion of the height of its peripheral wall for receiving a liquid forced thereinto in a specified amount at a time and a discharge outlet provided by a lower-end opening of the peripheral wall, and a liquid pushing-out rod slidably fitted in the nozzle body so as to open and close the inlet.
- the liquid in the nozzle body is wholly pushed out by the rod to fill a container with the completion of one cycle of filling operation.
- the liquid forced out will partly adhere to the rod and remain thereon.
- the main object of the present invention is to provide a nozzle for filling a liquid in specified amounts which comprises a tubular nozzle body having an inlet at an intermediate portion of the height of its peripheral wall for receiving the liquid forced thereinto in the specified amount at a time and a discharge outlet provided by a lower-end opening of the peripheral wall, and a liquid pushing-out rod slidably fitted in the nozzle body so as to open and close the inlet, the nozzle being characterized as defined in Claim 1.
- the liquid filling nozzle of the present invention With the liquid filling nozzle of the present invention, at least the lower end surface of the rod is so treated as to be hydrophobic and therefore will not permit the adhesion of the liquid thereto. If the liquid adheres to the rod and falls off inadvertently, the liquid is likely to adhere to the surface of the container to be sealed to result in imperfect sealing, or is likely to adhere to the container transport holder or the like to entail the problem of impaired sanitation, whereas the present invention has obviated such problems.
- the illustrated filling apparatus comprises a tank 12 disposed above a container conveyor 11 for containing the liquid to be filled, a vertical filling pipe 13 connected at its upper end to the bottom wall of the tank 12, a horizontal check cylinder 17 intersecting an upper portion of the filling tube 13 at right angles therewith, housing a piston 15 therein and provided with a jacekt 16 for preventing the liquid from solidifying, the piston 15 having a fluid channel 14 extending therethrough, a horizontal metering cylinder 19 projecting leftward from the lower portion of the filling pipe 13 and having a piston 18 therein, a movable filling pipe 22 rockably suspended from the lower end of the filling pipe 13 and provided with a jacket 21 for preventing the liquid from solidifying, and a filling nozzle 23 attached to the lower end of the filling pipe 22.
- the filling pipe 13 is provided at its lower end with a horizontal cylindrical member 24 for suspending the filling pipe 22.
- the suspending member 24 has a communication channel 25 which has one end opened leftward for communication with the filling pipe 13 and the other end opened downward.
- a horizontal rotary tube 26 is fitted in the suspending member 24 so as to cover the downward opening of the channel 25.
- the filling pipe 22 has an upper end connected to the tube 26.
- the filling nozzle 23 comprises a tubular nozzle body 33, and a rod 34 for pushing out the liquid to be filled.
- the nozzle body 33 has an inlet 31 formed at an intermediate portion of the height of its peripheral wall and connected to the lower end of the filling pipe 22, and a discharge outlet 32 provided by a lower-end opening of the peripheral wall.
- the rod 34 is slidably fitted in the nozzle body 33.
- a hydraulic cylinder 36 Connected by a yoke 35 to the upper end of the nozzle body 33 is a hydraulic cylinder 36, which has a piston rod 37 extending downward into the yoke 35.
- the pushing-out rod 34 has an upper end projecting upward beyond the nozzle body 33 and connected to the piston rod 37.
- the lower end surface of the pushing-out rod 34 has a projecting tapered face 41 at an outward portion thereof and a recessed conical face 42 at an inward portion thereof.
- An annular flat face 43 is formed at the boundary between the tapered face 41 and the conical face 42.
- the tapered face 41, the conical face 42 and the flat face 43 are all formed with a polytetrafluorethylen (PTFE) layer 44.
- PTFE polytetrafluorethylen
- the check piston 15 In the state shown in FIG. 1, the check piston 15 is in its leftward limit position to hold the check cylinder 17 open, the metering piston 18 is in its rightward limit position, and the liquid pushing-out rod 34 is in its lower limit position, holding the inlet 31 and the discharge outlet 32 closed.
- the metering piston 18 When the metering piston 18 is moved leftward in this state, the liquid to be filled flows out of the tank 12 into the filling pipe 13.
- the check piston 15 Upon the metering piston 18 reaching its leftward limit position, the check piston 15 is moved rightward to close the check cyinder 17, and the pushing-out rod 34 is raised to open the inlet 31 and the outlet 32.
- the metering piston 18 is then moved rightward, whereby the liquid in the filling pipe 13 is forced through the inlet 31 into the nozzle 23, further discharged from the outlet 32 and filled into a container C as transported to a position below the outlet. If the nozzle 23 is rocked over a predetermined range when the liquid is delivered from the discharge outlet 32, the liquid fills the container C to a flat level without forming an upwardly bulging shape inside the container C.
- the metering piston 18 reaching its rightward limit position the feed of liquid from the filling pipe 13 is discontinued, where-upon the pushing-out rod 34 is lowered to force out the liquid from the nozzle 23.
- One cycle of filling operation is completed when the rod 34 reaches its lower limit position.
- the PTFE layer 44 is formed by coating the lower end surface of the pushing-out rod 34.
- PTFE has a hydrophobic property, therefore repels the liquid even if the liquid tends to adhere to the rod end surface and consequently renders the end surface free from the liquid.
- this layer may be replaced by a PTFE layer.
